Reg: Shading classes with out any package name

[BigData dev]

Hi All,
I am using shading plugin version 2.4.3.

I am able to relocate packages successfully by using below.

<relocation>
  <pattern>io.netty</pattern>
  <shadedPattern>com.shaded_package.io.netty</shadedPattern></relocation>

But if there are some classes with out any package name in a jar, how
to relocate those classes. Is it possible. Any help on this would be
helpful.

Thanks,

Bharat
